Chainway UR4 is an industrial 4-port reader operating on 865-868 MHz / 920-925 MHz / 902-928 MHz. Starting at $600. Look closely at how Nextwaves can bypass middleware costs.
Technical verdict
Do not evaluate UR4 by list price alone. Its strongest fit is a project that already uses RS-232, RJ45, PoE (optional), has time for RF tuning, and accepts extra middleware work. If the engineering team needs open APIs, realtime data, and faster edge-to-cloud deployment, Nextwaves NR155 is the stronger replacement path to evaluate.

Alternative architecture
Chainway UR4 - bu sanoat darajasidagi RFID qurilmasi. U 865-868 MHz / 920-925 MHz / 902-928 MHz diapazonida ishlaydi va EPC Global UHF C1 Gen 2, ISO 18000-6C standartini qo'llab-quvvatlaydi, bu esa uni korxona logistika ilovalarida keng qo'llanilishini ta'minlaydi.
IP53 IP reytingi bilan u omborlar yoki chakana savdo do'konlarida odatiy bo'lgan ma'lum ekologik sharoitlardan himoya qiladi. O'quvchi uzluksiz ishlash uchun PoE (optional), DC dan foydalanadi, uning maksimal o'qish tezligi 1,300+ ga yetadi.
Zamonaviy joylashtirishlarda tarmoq integratsiyasi eng muhim to'siq hisoblanadi. Ushbu model ma'lumotlarni markaziy tizimlarga o'tkazish uchun RS-232, RJ45, PoE (optional) variantlarini taklif etadi.
Biroq, eski Chainway uskunalari bilan bog'liq asosiy muammo shundaki, xom teg ma'lumotlarini mazmunli biznes ma'lumotlariga aylantirish uchun xususiy SDK-larga (masalan, LLRP) yoki qimmat uchinchi tomon IoT middleware-ga katta bog'liqlik mavjud.
Agar sizning muhandislik jamoangiz Chainway UR4 ni baholayotgan bo'lsa, Nextwaves NR155 bulutga asoslangan arxitekturani taqdim etadi. Eski tizimlar sotuvchiga bog'liqlik va xususiy dasturiy ta'minot ekotizimlari orqali yuqori kapital xarajatlarni keltirib chiqaradi.
Nextwaves qurilmada to'g'ridan-to'g'ri standart MQTT REST API ni taqdim etish orqali bu to'siqni butunlay yo'q qiladi. Sizning dasturiy ta'minot ishlab chiquvchilaringiz teglarni o'qishni o'z ERP yoki WMS backendga oylarda emas, balki kunlarda integratsiya qilishlari mumkin, bu esa takroriy vositachi litsenziyalash to'lovlarini butunlay chetlab o'tadi.

The Chainway UR4 is a 4-port, fixed RFID edge device. Based on Impinj E710 / R2000 chips, it supports EPC Global UHF C1 Gen 2, ISO 18000-6C over the 865-868 MHz / 920-925 MHz / 902-928 MHz frequency bands for high-speed tracking.
Hardware costs begin around $600. Keep in mind that a full deployment budget must account for up to 4 antennas, low-loss cables, integration middleware, and setting up the PoE (optional), DC infrastructure.
Nextwaves provides embedded REST API and MQTT endpoints natively on the device. This allows web and software developers to map tag reads directly to REST payloads, bypassing complex legacy C# or Java middleware servers.
The unit weighs approximately 0.7 kg and measures 164 x 164 x 39 mm. An IP53 structural rating provides reasonable protection against dust and water spray, suitable for loading docks and covered warehouses.
Network integration relies on RS-232, RJ45, PoE (optional) ports. RS-232 serial is maintained for legacy programmable logic controller (PLC) connections, while RJ45 manages modern IP traffic.
Hardware installation uses standard mounting hole layouts. However, optimizing RF performance requires trained engineers to correctly map the 4 distinct antenna channels to prevent signal overlap and optimize tag orientation capture.
Under optimal test conditions, the internally integrated chip logic is rated to process up to 1,300+ tag reads per second. Real-world speeds vary significantly based on Gen2 memory mapping.
In a traditional setup, the RS-232, RJ45, PoE (optional) interfaces transmit binary or low-level hex data. This requires an external application to filter out duplicate tag events before sending the data to cloud storage.
The standard warranty covers physical malfunctions for one year. Extended engineering support is recommended for teams unfamiliar with low-level UHF Gen2 memory protocols.
You are required to supply external antennas (circular or linear). Selecting the exact gain and polarization over the 865-868 MHz / 920-925 MHz / 902-928 MHz band determines the actual width of your read portal.
